A nurse is preparing to administer haloperidol 3 mg IM. Available is haloperidol injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Dose of haloperidol: 3 mg Concentration of haloperidol injection: 5 mg/mL Calculate the volume of haloperidol injection to be administered: Volume = Dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 3 mg / 5 mg/mL Volume = 0.6 mL
